A paper sheet handling device (a banknote handling device) includes a paper sheet detection device (a tracking sensor) configured to detect a paper sheet, and a handling unit performing handling related to the paper sheet based on the time when the paper sheet detection device detects an end of the paper sheet. The paper sheet detection device includes a pair of rolling bodies (rollers) facing each other, disposed on a transport path transporting the paper sheet, and configured so that the paper sheet passes therebetween, and a detection unit detecting displacement of the rolling bodies when the paper sheet passes between the pair of rolling bodies to detect the paper sheet.

Paper sheet processing device and paper sheet processing method

A paper sheet recognition apparatus can generate a subtracted reflective light image without increasing detection time. To that end, the operations of sensors are controlled in a plurality of phases. The phases include a phase (reflected infrared light) in which a first light emission unit emits light, a second light emission unit emits no light, and an optical sensor detects reflective light. In another phase, (reflected infrared light) the first light emission unit emits no light, the second light emission unit emits light, and the optical sensor detects reflective light. In at least one of these phases, a light emission unit emits light, and an optical sensor detects transmissive light.

Paper sheet identification device and paper sheet identification method

By overlapping lighting timings of light sources that emit lights of a plurality of different wavelength bands including a wavelength band of at least a visible light region and an infrared light region, the lights of the plurality of the different wavelength bands including the wavelength band of at least the visible light region and the infrared light region are emitted on a banknote while securing an overlap in timings thereof. Moreover, by using light receiving elements each including a bandpass filter that allows only light of a wavelength range that corresponds to the wavelength band of each of the light sources, received light intensities of the light of the wavelength range that corresponds to the wavelength band of each of the light sources are acquired simultaneously, and image data are formed based on the received light intensity of every acquired wavelength band.

Light receiving sensor, sensor module, and paper sheet handling apparatus

Light is emitted on one side of a paper sheet, which is being transported on a transport path, from a first light source, and light is emitted on other side of the paper sheetfrom a second light sourceand a fourth light source. A first light receiving sensorreceives a first reflected light, which is the light emitted by the first light sourceand reflected from the one side of the paper sheet. A second light receiving sensorreceives a second reflected light, which is the light emitted by the second light sourceand the fourth light sourceand reflected from the other side of the paper sheet, and receives a transmitted light that is the light emitted by the first light sourceand that has passed through the paper sheet. With this, satisfactory reflection image and transmission image of the paper sheet can be acquired while realizing the downsizing of the device.

Image acquisition device and image acquisition method

The object is to avoid degradation of magnetic detection precision arising due to magnetization of transport rollers used for transporting a paper sheet. A paper sheet magnetic detection apparatus that detects a magnetic material in the paper sheet by using a magnetic sensor includes a transport path that transports paper sheets one by one; at least one magnet that is used in the detection of the magnetic material by the magnetic sensor; and a plurality of transport rollers that are arranged near the magnetic sensor and that transport the paper sheet in the transport path. Outer peripheral surfaces of the plurality of transport rollers that face the transport path are made of a non-magnetic material.

A first light receiving sensorreceives a first reflected light, which is the light emitted by the first light sourceand reflected from the one side of the paper sheet. A second light receiving sensorreceives a second reflected light, which is the light emitted by the second light sourceand the fourth light sourceand reflected from the other side of the paper sheet, and receives a transmitted light that is the light emitted by the first light sourceand that has passed through the paper sheet.

To detect a fluorescent light and a phosphorescent light emitted from a paper sheet with a high precision, a fluorescence and phosphorescence detecting apparatus includes two sensor units. Each sensor unit includes a light source that emits an ultraviolet light on the paper sheet, an image sensor that captures images of the fluorescent light and the phosphorescent light excited on the paper sheet by irradiation of the ultraviolet light, and a light receiving lens that guides the fluorescent light and the phosphorescent light excited on the paper sheet to the image sensor. The two sensor units are arranged above and below the transport path and opposing each other across the transport path, and the light receiving lenses and the image sensors in the two sensor units are off-set along a transport direction of the paper sheet.

Fluorescence and phosphorescence detecting apparatus

The present invention relates to a paper sheet discriminating device which irradiates lights of two or more wavelengths from a light source and receives transmitting lights which transmit through a paper sheet and performs the discrimination in response to light receiving signals, and the device includes a reference value setting apparatus which adjusts a light emission quantity of the light source and stores the output value of the photo sensor which directly receives light from the light source as an adjustment reference value, and an adjustment apparatus which adjusts the light emission quantity of the light source such that the output value of the photo sensor which directly receive light from the light source is made to agree with the stored adjustment reference value.
